As I said there is no way of getting only "http://hola"; which is the value. I
don't know what I'm doing wrong but cannot get it.
Example with all possible functions:
String b = "http://hola^^http://www.w3.org/2001/XMLSchema#anyURI";;
Literal a = (Literal) ResourceFactory.createTypedLiteral(b,
XSDDatatype.XSDanyURI);
System.out.println(a.getDatatype());
System.out.println(a.getLexicalForm());
System.out.println(a.getDatatypeURI());
System.out.println(a.getString());
System.out.println(a.getValue());
System.out.println(a.toString());
Output:
Datatype[http://www.w3.org/2001/XMLSchema#anyURI -> class java.net.URI]
http://datypic.com/fraf1^^http://www.w3.org/2001/XMLSchema#anyURI
http://www.w3.org/2001/XMLSchema#anyURI
http://datypic.com/fraf1^^http://www.w3.org/2001/XMLSchema#anyURI
http://datypic.com/fraf1^^http://www.w3.org/2001/XMLSchema#anyURI
http://datypic.com/fraf1^^http://www.w3.org/2001/XMLSchema#anyURI^^http://www.w3.org/2001/XMLSchema#anyURI
If I run the same code using a integer:
a =
ResourceFactory.createTypedLiteral("\"5\"^^http://www.w3.org/2001/XMLSchema#int";,
XSDDatatype.XSDint);
I get an exception: org.apache.jena.datatypes.DatatypeFormatException.
I'm suggesting there should be a function like createTypedLiteral(String
literal) where literal is a well-formatted literal. Then using the parsing from
^^ internally will be able to extract the type and somehow obtain the same
outcome as the createTypedLiteral(String, Datatype) function.
I guess that internally there should be such a function.
Thanks a lot for your help and understanding.
See you
